A cool game mode I thought about

Okay so its like a siege type of thing. Where the defending team is always a one shot kill, while the attacking cannot actually attack the defending team but must auto attack their nexus and gets teleported to their spawn point as soon as they do. The defending team only has the base and nexus turrets while the attacking have none and all turrets deal 1 shot kills but they are escapable, as I will explain later.

The deffending team is all Xerath that can only use q and r. With no mana cost and q being no cd with r with 90 sec cd. The Xerath team get a trinket thats like the blue, but stack up to 5 times 30 sec cd and more sight range than a normal ward, but half the cast range.

The attacking is all Zed that can only use w and r. W having a 5 sec cd(after second cast or shadow time out), and r having a 90 sec cd. I do belive zed become invisible to all attacks in ani of ult? If not that he does this time. The zed team get a trinket to become invisible like evelynn for 10 seconds. with a 60 sec cd

Minions do spawn on both teams and for every minion the xerath can get to zed's nexus (xerath cannot hit nexus) it removes 5-10 sec (idk w/e) from total time. As for the zed's team, the turrents do not hit the minions and for every minion that hits the nexus its 2 points for zed.

Every time xerath kills a zed it takes 20 secs off time from time. If zed can hit xeraths nexus they get 5 points.

As for the winning condition. The game starts at 10 mins and counts down if the zed team can get 100 points.

Thats about it for my idea, tell me what you think about it.
